Drive down about 5 more feet to allow for seasonal water level changes. Do not drive down too far or you may push your sand point past the water-bearing formation.
Read MoreBasically, a water well is a hole or shaft down to a water-bearing layer of sand or gravel or a crack in the rock. Fortunately for the well driller, most of the fresh water beneath the surface of the ground occurs within 200 feet. Unless your area is famous for deep, dry holes, the chances are that by a little exploratory drilling you can find
